 Exhibit 4.5 

ALLOCATION AGREEMENT 

This Allocation Agreement (the “Agreement”) is made and entered into as of November 8, 2015, by and between AppDynamics,
Inc., a Delaware corporation (the “Company”) and Adage Capital Partners, LP (the “Investor”). All capitalized terms not otherwise defined shall have the respective meanings ascribed thereto in Section 4. 

WHEREAS, concurrently with the execution of this Agreement, (i) the Company and (ii) the Investor and certain other investors
(collectively, the “Series F Investors”) are executing an Amended and Restated Series F Preferred Stock Purchase Agreement (the “Series F Agreement”) which amends and restates that certain Series F
Preferred Stock Purchase Agreement dated October 16, 2015 (the “Prior Agreement”), pursuant to which the Investor purchased shares of the Company’s Series F Preferred Stock (the “Series F
Stock”); 
 WHEREAS, the purchase and sale of the Series F Stock pursuant to the Series F Agreement and the Prior Agreement is
referred to herein as the “Series F Financing”; and 
 WHEREAS, in consideration of the Investor acting as a lead
investor in the Series F Financing, the Company agrees to make certain arrangements to allow the Investor to participate in a future offering of the Company’s Common Stock in accordance with the terms and conditions contained herein. 

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth herein, and for other good and valuable consideration, the
parties hereto agree as follows: 
 1. Allocation of Shares and Private Placement Right. 

1.1 Allocation. Subject to the requirements of the Securities Laws and Regulations and subject to the other provisions of this
Agreement, the Company agrees to use its reasonable best efforts (including reasonable cooperation with respect to obtaining applicable regulatory clearances) to provide Investor with the right, but not the obligation, to purchase from the Company,
in a separate and contemporaneous private placement transaction exempt from registration with the SEC (the “Private Placement”), up to the Investor Maximum Allocated Shares on the terms set forth in this Agreement. Any such purchase
of shares of Common Stock shall be at the same price per share at which such shares of Common Stock are being offered to the public pursuant to the Company’s registration statement with respect to a Qualified IPO. 

1.2 Notice of Qualified IPO. Within fifteen (15) business days after the Company first submits to, or files with, the SEC a
registration statement covering shares of its Common Stock for a Qualified IPO , the Company will notify the Investor in writing (the “Offering Notice”) of the Company’s intent to undertake the Qualified IPO, which shall
include, if known at the time of such Offering Notice, (i) the approximate date that the Company expects to print and distribute preliminary prospectuses relating to the Qualified IPO, (ii) the anticipated closing date of the Qualified IPO
and (iii) the actual number of shares of Common Stock to be allocated to the Investor. The Company and the Investor acknowledge that the schedule will be based upon the Company’s reasonable best estimate at the time of the Offering Notice
but that such schedule is subject to substantial revision based upon market conditions, disclosure issues that may arise during the preparation of the registration statement, interaction with the SEC regarding the registration statement and other
factors. 








 1.3 Preliminary Indication of Interest. No later than fifteen (15) business days
after the delivery of the Offering Notice (the “Response Period”), the Investor may provide the Company with a non-binding written statement setting forth the aggregate dollar amount that the Investor is interested in purchasing in
the Private Placement. The Company and the Investor acknowledge that this indication of interest is not intended to be an offer to purchase from the Investor but merely an indication of interest to assist the Company in structuring the Private
Placement and preparing appropriate disclosure in the registration statement. The failure by the Investor to notify the Company within the Response Period of its interest in purchasing shares in the Private Placement shall terminate the
Investor’s right to purchase shares pursuant to the Private Placement, unless the Qualified IPO is not completed within one hundred eighty (180) days of the Offering Notice; in which case the Company shall not complete a Qualified IPO
without again complying with the provisions of this Section 1. 
 1.4 Final Indication of Interest. No later than the time at
which the managing underwriters for the Qualified IPO obtain final indications of interest from potential purchasers in the Qualified IPO (the “Pricing Deadline”), the Investor must provide the Company with the Investor’s final
indication of interest setting forth the number of shares of Common Stock that the Investor is interested in purchasing in the Private Placement. The failure by the Investor to notify the Company by the Pricing Deadline of its interest in purchasing
shares in the Private Placement shall terminate the Investor’s right to purchase shares pursuant to the Private Placement, unless the Qualified IPO is not completed within one hundred eighty (180) days of the Offering Notice; in which case
the Company shall not complete a Qualified IPO without again complying with the provisions of this Section 1. 
 1.5 Compliance with
Securities Laws and Regulations. Notwithstanding the Company’s exercise of its reasonable best efforts in accordance with Section 1.1, in the event that any such Private Placement would, in the Company’s reasonable judgment, based
on the advice of counsel for the Company and following consultation with the Investor, be deemed invalid as a private placement under the Act for any reason (including but not limited to by reason of the doctrine of “integration” with the
Qualified IPO) or would otherwise conflict with any Securities Laws and Regulations or give rise to any other legal impediment or legal requirement that would prevent or materially delay the consummation of or unreasonably interfere with the
Qualified IPO, then the Private Placement shall not occur and the Company, on the one hand, and the Investor, on the other hand, shall have no liability or obligation to one another in connection therewith; provided, however, that in such event the
Company will discuss good faith alternatives with the Investor and use reasonable best efforts to provide the Investor with a substantially equivalent investment opportunity. 

1.6 Closing. The closing of the Investor’s purchase of shares in the Private Placement pursuant to this Agreement shall take place
substantially simultaneously with the closing of the Company’s sale of shares to the underwriters in the Qualified IPO. The Company and the Investor agree that the terms and conditions of the Investor’s purchase of shares in the Private
Placement pursuant to this Agreement will be memorialized in, and governed by, a mutually agreeable written stock purchase agreement between the Company and the Investor (the “Private Placement SPA”) with customary terms and
provisions for such a transaction. The Investor and the Company agree to sign such other mutually agreed upon reasonable and customary documents, and take such other reasonable and customary actions as other party may reasonably request, in
connection with such closing. 
 1.7 Conditionality. The right of the Investor to purchase shares in the Private Placement under this
Section 1 shall be conditioned, in each case, upon the completion of the Qualified IPO. The Company may withdraw any registration statement for a Qualified IPO at any time without thereby incurring any liability to the Investor or any permitted
assignee of the Investor or other party that has been apportioned rights hereunder.

 1.8 Registration Rights. Any shares purchased by the Investor in the Private Placement
shall be deemed to be “Registrable Securities” as such term is defined in Section 1.1 of the Investors’ Rights Agreement. 

2. Qualified IPO Only. For the avoidance of doubt, subject to the obligations of the Company set forth in the proviso to
Section 1.5, the right of the Investor to purchase shares in the Private Placement under this Agreement shall only be applicable to any Private Placement conducted in connection with a Qualified IPO and not to any other offering of securities
by the Company, either before or after the consummation of the Qualified IPO. In the event that the Company undertakes to offer securities pursuant to a firm commitment underwritten public offering under the Act that does not qualify as a Qualified
IPO, the Investor shall have no rights or obligations under this Agreement in respect of, or as a result of, such offering, including without limitation, the rights and obligations described in Section 1 above, but this Agreement and all rights
and obligations hereunder shall remain in full force and effect until terminated pursuant to Section 6.7 below. 
 3. Restricted
Securities. 
 3.1 Restricted Securities and Market Stand-Off Terms. The Investor hereby agrees that any shares of Common Stock
acquired by the Investor pursuant to this Agreement shall be deemed to be “Restricted Securities” as such term is defined in Section 1.1 of the Investors’ Rights Agreement and as such shall be subject to Sections 2.8, 2.10
and 2.12 of the Investors’ Rights Agreement. 
 3.2 Legend. In order to enforce the foregoing covenant, the Company shall have
the right to place the following restrictive legend on the certificates representing the shares subject to this section and to impose stop transfer instructions with respect to such shares until the end of such period:

 3.3 Additional Agreement. The Investor acknowledges its obligation pursuant to
Section 2.10 of the Investors’ Rights Agreement to execute a market standoff agreement with the underwriters in an Initial Public Offering (as defined in the Investors’ Rights Agreement) in customary form and consistent with the
